In some embodiments, the device also includes a speaker or a vibrationmotor to signal to the user. Also, in some embodiments, the deviceincludes one or more manual input devices, for example, a capacitanceslider, buttons, keypad, scroll wheel, jog wheel, or any other inputdevice. In still other embodiments, the device includes a GPS device. Insome embodiments, the device includes at least one database. In otherembodiments, the device includes optical character recognition software.

Referring now to FIG. 2B, in this embodiment, the device 60 is a medicaldevice. In one embodiment, the medical device is an infusion device. Inthe embodiment shown in FIG. 2B, the infusion device 60 includes adisplay 62, a housing 64 and manual input elements, a capacitance slider66 and buttons 68. In other embodiments, the device 60 may include onlyone of these manual input elements, but in other embodiments, the device60 includes all shown. As described above, the device 60 additionallyincludes at least one technological means for communication with thefood item. In some embodiments, this technological means is an RFIDreader, however, in other embodiments; the technological means is any ofthose described above.

Referring now to FIG. 2C, in this embodiment, the device 60 is a medicaldevice. In one embodiment, the medical device is a remote controller fora continuous glucose monitor and/or for an infusion device. Thecontroller device 60 includes a display 62 and a housing 64. Thecontroller 60 may also include at least one manual input device 68. Inother embodiment, a slider (as shown in FIG. 2B) may be included. Asdescribed above, the device 60 additionally includes at least onetechnological means for communication with the food item. In someembodiments, this technological means is an RFID reader, however, inother embodiments; the technological means is any of those describedabove.

Also, in one exemplary embodiment, the controller 60 includes a stripglucose reader (i.e., a glucose meter) 70. In one exemplary embodiment,the controller 60 is a remote controller for an infusion device, e.g.,an insulin pump. In one embodiment, the controller 60 is a continuousglucose monitor handheld/controller. In still another embodiment, thecontroller 60 is a both a remote controller for a infusion device and acontroller for a continuous glucose monitor.

The controller 60 embodiment includes the capability of transferringinformation or commands to the medical device (e.g., insulin pump) basedon the food information. For example, the controller 60 may accessinformation related to the food item from a database internal to thecontroller, and the user inputs a desired amount of ingestion. Thecontroller 60 may, using the food item information, calculate the amountof bolus the user should infuse to cover the requested amount of fooditem. This bolus amount can then be remotely sent to the insulin pumpworn by the user and the insulin pump will then infuse that bolus amountof insulin into the user.

Other methods include the user entering a blood glucose reading (i.e.,in the embodiment shown in FIG. 2C, the user uses the strip reader todetermine the blood glucose, thus, the reading is already in thecontroller 60, or, in the case where the controller 60 is a controllerfor a continuous glucose monitor, again, the controller 60 already hasthe user glucose reading) and the controller 60 recommends a food itemand/or an amount of a food item identified to the controller 60 based onthe food item and blood glucose reading.

Various embodiments are shown in the figures. However, these are notlimiting, as other embodiments containing combinations of the elementsdescribed above will be apparent to one of ordinary skill in the art.

In some embodiments, the electronic or medical device is designed toread an identifying device on the food item or associated with the fooditem, giving identification. Referring to FIG. 3, in one embodiment, thedevice 50 receives information from the food item 60 and reads theidentification of the food item. In this embodiment, the device 50includes an RFID reader and the food item 60 includes an RFIDtransponder. The food item information communicated to the device isdescribed in more detail below, however, can be any information,including but not limited to nutritional information, price information,and/or location. In some embodiments, where the device 50 is within acommunicable range from a food item 60, the food item will “call out” tothe device and the device will “wake up” or otherwise signal to the userthat a food item 60 is nearby. Where a food item 60 includes an RFIDtransponder, the radio signal is broadcast continuously. However, adevice 50 may be programmed to wake-up or signal to the user where thefood item 60 within communicable distance is one selected by the user inthe “user profile database”. Thus, the device 50 may be customizable toonly signal to the user where the user is within a pre-selected distanceto pre-selected food items.

Referring now to FIG. 4A, other technological means of the devicerecognizing a food item are shown. The means shown in FIGS. 3-4A are notmeant to be an exhaustive list of means, but are a few embodiments.Included in FIG. 4A are bar codes where the device 50 includes a barcode scanner and can read the bar codes from the food items 60. Opticalrecognition codes where the device 50 includes a reader, and where thedevice 50 includes a camera and the device recognizes the item throughoptical recognition. Any means of identification or transferring thefood item information is available in alternate embodiments.

As described above, the device may be any consumer electronic device ora medical device. Consumer electronic devices include a cell phone, PDA,watch, an iphone, an icart, or a dedicated terminal.

The type of technological means for communication in the device variesdepending upon the desired means for communications. For example, if thedesired communication is through wireless communication, then a radiomay be used. If the desired communication is through bar code, then abar code scanner may be used. If the desired communication is throughoptical recognition, then a camera may be used.

The device housing can be any shape or size desired. The housing can bemade from plastic, aluminum or any other type of material. Additionally,the housing can be shaped to fit within any holding device. The CPU canbe any size desirable size and can include any type of software. Thedevice can also include RAM of any size. As discussed above, in someembodiments, the device includes a feature for manual entry ofinformation. This feature can be a capacitance slider or pad, at leastone button or a keypad, a scroll or jog wheel, etc. In otherembodiments, any feature allowing manual user interaction with thedevice is considered.

FOOD ITEMS. The devices described above are used in a food managementcapacity. However, in some embodiments, the devices include additionalfunctionality other than food management. Also, it will be understoodthat although the functions, methods and systems described herein aredescribed with respect to food management, in other embodiments, thedevices described herein can be used to manage anything, including anytype of consumer product. However, as an exemplary embodiment, use ofthe device, system and methods will be described herein with respect tofood management. Other embodiments will be readily apparent to one ofordinary skill in the art.

The food item to be managed will either communicate directly with thedevice or indirectly with the device. In either embodiment, informationregarding the food item will be imparted to the device.

As used herein, the term food item includes any edible item, whether inwhole or part, and whether in a natural or artificial state. In someinstances, the food item is entirely or partly artificial, i.e., notnaturally occurring. The food item need not be nutritive, but can benon-nutritive. However, in all the cases, the food item is capable ofingestion by an animal.

Thus the food items includes vitamins, supplements, flavorings,colorings, herbal, prepared, frozen, fresh, raw, dried or powdered fooditems as well as beverages, which include juice, waters, milks, spirits,teas, coffees, carbonated sodas and any other drinkable substance. Othertypes of food items are contemplated including any item, whetherregularly referred to as food or otherwise, capable of ingestion by ananimal including a human.

Information regarding the food item includes nutritional information,serving size information, inventory information, location, pricing orother information, for example, pairing and volumes of food items thatare put together in a beneficial manner, for instance, in a recipe orpairing a cheese or dish with a wine. Additionally, information relatedto recommendation for ingesting is also included in some embodiments.

The food item can be a food item in a vending machine, on a store shelfor in a particular pre-prepared dish, for example, in a restaurant.However, the food item can be any food item in which a consumer iscontemplating buying or ingesting either presently or at a later. Inother embodiments, the food item is not contemplated by the consumer butrather, the device recommends the consumer buy or ingests the food basedon pre-programmed parameters, which will be discussed in greater detailbelow.

It should be understood that the term consumer includes an individualperson, or a company or organization. The food item is not necessarilybeing bought or ingested at the time the device presents information tothe consumer or manages the food. It should be understood that the termfood item means either the physical item itself or the item in nameonly.

SIGNALS. The food item interacts with the device through a signal. Thesignal can be a radio signal, a bar code, an electrical signal, anoptical signal or any form of a manual input that identifies the fooditem to the device. Thus these signals can be, but are not limited to,radio, electronic, optical, manual or bar code.

The signal can be automatic or requiring instigation by either the fooditem or the device. Thus, the signal between the food item and thedevice may be instigated by the food item when the device comes within apredetermined distance of the food item. In another example, the devicemay request the information regarding a food item.

The signal may include any amount of information. Information includes,but is not limited to, an indication that the food item is withinproximity, nutritional information, ingredients information, pricinginformation, recommendation information, acceptability, or that the fooditem exists.

The signal may include the entirety of the information of the food itemto the device, or in other embodiments, the signal relates to an entryin a database. In this embodiment, the signal will trigger informationfrom a database to be sent to the device. In some embodiments, theinformation sent is all of the information the database has on the fooditem. In other embodiments, the information sent is only a part of theinformation. The part sent is dependent on parameters entered into thedevice or the database and is based on the user desires (e.g., part ofthe “user profile”). For example, in some embodiments, the user may onlydesire information that the food item exists. In other embodiments, theuser desires knowledge of the number of the food items existing in aparticular location. In other embodiments, the user desires pricinginformation only. In other embodiments, the user desires carbohydrateinformation of the food item. In other embodiments, the user desiresknowledge of the presence of a particular ingredient in the food item.In other embodiments, the user desires information of whether the fooditem is included in their pre-programmed diet management program and/orwhether the food item conflicts with a diet management program orinteracts with a drug the user is taking. All of these embodiments canfound in certain embodiments in any combination, and still, otherembodiments regarding the particular information on the device arecontemplated. These embodiments are discussed in further detail below.Still other embodiments are contemplated that will be apparent to one ofordinary skill in the art.

In some embodiments, the signal may be manually entered into the device.In this case, the manual entry triggering identification of the fooditem can vary from a UPC code to any alphanumeric, purely alpha orpurely numeric code in any length varying from 1 to any number ofsignificant figures. The entry may include a system designedspecifically for a particular brand of food, or for a particular type ofdietary management. The combination to be entered into the device may belocated on the food item itself, or may be available as a look-up tableon the device. In other embodiments, the entry may be anything that ispre-assigned and determinable by a user.

In one embodiment, the user manually enters a 3 digit alpha numeric codelocated on the food item, followed by the number of serving sizes. Thenumber of serving sizes can either be the number in the food item theyare purchasing, or the number in the food item they are planning oneating. In any case, the 3 digit alphanumeric code will present the userwith food item the pre-determined food item information, including, insome embodiments, recommended serving size. In alternate embodiments,the code is a 2-digit code, or a 2 digit alphanumeric code. In someembodiments, the code is a product or brand specific code. In stillother embodiments, the code is located on the product itself, or is alook up in a database.

INFORMATION. As described above, the information regarding the fooditems varies with the embodiments. The information can be anyinformation a user desires with respect to the food item. Theinformation communicated in response to the signal is pre-determined,i.e., based on user parameters or other parameters, for example, aparticular company, store or organizations parameters.

As described above, the information may vary anywhere from an indicationof the presence of the food item, to detailed information regarding thefood item or anything related to the food item. In the embodiments whereonly the presence of the food item is indicated in the signal, thedevice may alarm (audio or vibration), wake-up, light up, or otherwiseindicate through the UI or visual, audio or other signal the presence ofthe food item. In other embodiments, the presence of the food item iseither solely or additionally, indicated through a light, alarm orother, indication on a store shelf, vending machine or other locationwhere a food item can be displayed or through any means where a fooditem can be sold (i.e., on a menu or other).

However, in those embodiments, either in addition to the signal that thefood item is present or on its own, additional information iscommunicated. It is these embodiments that will be described in moredetail below. Again, these embodiments may be in additional to thesignal of the presence of the food item or in lieu of same.

The information itself is either stored in a database or communicateddirectly through the signal. Thus, in the embodiment where the signal issent via RFID, or radio communication, the signal may include a code oridentification of the food item which is then used to pull-up, look-upor otherwise, information in a database related to that food item, or,in alternate embodiments, the food item information is directlycommunicated in the RFID or radio signal.

THE DATABASE. The database may be located anywhere in which the devicecan access the information contained on the database. In one embodiment,the database may be located on the device. In other embodiments thedatabase may be located on a network, either the internet or an areanetwork. In the embodiments where the database may be located remotely,the database may be accessed via a wireless signal. In some embodiments,although the database may be stored on the device itself, the databasemay be updated via wireless or wired connected to the databaseelsewhere, thus, additional information may be accessed when requestedor updated automatically.

Thus, the device may retrieve the food item information either byaccessing it through a wireless connection or by retrieving theinformation from its internal RAM. The RAM is either part of the CPU, oraddition RAM is added separately.

The database may contain information related to the food item for use infood item management. The information includes, but is not limited to,that related to nutritional or ingredient information, price, locationof items, etc, described in more detail above. However, the informationmay also include information that is user specific or demographicspecific. For example, the database may contain information related tothe preference of the particular food item for those with specific dietrestrictions. These include, but are not limited to, those living withdiabetes, those with high-blood pressure, high cholesterol, overweight,specific allergies. Depending on the user, different information will besent to the device for the user to view.

The database may be used to track a user's habits, preferences, intakeor any combination thereof. The database may be used to suggest fooditems in response to a specific inquiry, i.e., based on a user enteredpreference or request. In one embodiment, the database is a learningdatabase.

The database includes information on from 1 food item to every food itempossible on the earth. The database can include any and all possibleinformation related to any one or more particular food item.

Each user of the database is identified in the database and hasparticular preferences recognized by the database. This is referred toas the user profile. The database presents information related to thefood item based on the user profile. The term “user” means an individualuser; a group of users, a company, an organization, a subset or anyother combination or type of predetermined subset.

These user profiles may be predetermined or learned. Thus, in theembodiment where the user is an individual, the user profile isparticular to that user. In the case where the user is an identifiablegroup, the user profile is predetermined by one representing the entiregroup.

Thus the device, together with the database, is used in food management.The device is capable of identifying the food item, and capable ofdetermining specific information regarding that food item eitherinternally (if the device received the information via signaltransmission from the food product itself or in the case where thedevice includes a database containing information for the food items) orindirectly through wireless communication with a database.

USER PROFILE. In addition to the description above, the user profile maybe entered through a central system, for example, a web page. The usermay update their profile or view it at any time using the Internet. Insome embodiments, any person may access or create their user profile. Inother embodiments, the user must be part of a private group to access orcreate a profile. The profiles may be accessed by any databaseprogrammed to do so. If the profiles are available on a web server, theprofiles may be accessed anywhere. However, in some embodiments, thedevice itself independently contains or stores the user profile and thedatabase. Thus, in these embodiments, the device may access only oneprofile.

The user profile may include but are not limited to information relatingto medical conditions, including allergies and diseases. Also, the userprofile may include, but is not limited to, any one or more of thefollowing: preferences, goals, and choices for the device to alarm,limit, prevent or recommend, are amongst other user profile options.

The user profile, in some embodiments, additionally may includefinancial information. This can include a budget or an allowance, aswell as an account. The device may be used as an electronic bank wherethe user may transfer funds to a vending machine or a store to purchasefood items. Additionally, because the user profile includes a number ofuser chosen limitations, those limitations may optionally be linked tothe account, preventing actual purchasing of particular food items. Inone embodiment, the financial information in the user's profile iscontrolled by a separate party, for example, a parent or guardian of theuser may control the finance of the user profile. In still otherembodiments, a third person has full control over a user's profile. Thiscan be a parent, guardian or a doctor or other medical professional.

FOOD MANAGEMENT. The combination of the food items, informationregarding the food item and the device allows for food management. Thedevice and information may provide the ability of the user to purchasethe food item, track the purchase of the food item, track the ingestionof the food item and determine information regarding the food item. Theinformation also may provide suggestions of food items to the user ofthe device. The combination of having user preferences and informationrelated to the food item allows for infinite combinations andpossibilities for food management, all which will be apparent to thoseof ordinary skill in the art. Exemplary embodiments of the use of thesystem are described below.

MULTIPLE DEVICE FUNCTIONS. In some embodiments, as mentioned above, thedevice includes other functions. For example, the device may be a cellphone, a medical device, a PDA, an iPOD, MP3 player or any otherelectronic device. In the case when the device includes additionalfunctions in addition to food management, the device may eitherintegrate the food management function with the additional functions, orelse include the food management function as an optional function.

MEDICAL DEVICE CONTROLLER EXAMPLE. In one embodiment, the device is amedical device controller, as shown in FIG. 2C. Although the exampledescribed below relates to the device being a medical device controller,in alternate embodiments, these same functionalities may be embodiedonto an infusion device or insulin pump. In these embodiments, the bloodglucose reading is either manually entered by the user, automaticallyupdated based on a continuous glucose monitor or blood glucose readingtaken by a glucose meter and automatically transferred to the insulinpump.

Referring now to FIG. 4B, the food management system, in one embodiment,is integrated with the controller's other medical functionality. Thus,where the controller is a remote controller for an infusion device,e.g., insulin pump, the insulin controller includes, as part of itsfunction, a tracking system of the amount of insulin on board, (“IOB”)which is the amount of insulin in the user's body at any given time.Using this information, as well as the information relating to the mostrecent blood glucose reading of the user and the user's specific insulinsensitivity information, the controller may calculate a recommendedinsulin dose for the particular user once the user enters the intendedintake of nutrition. However, in other embodiments of the controller,the controller tracks blood glucose and/or provides a glucose meter, andadditionally aids a person in selecting appropriate food items andserving sizes based on blood glucose and caloric intake (but not insulininformation).

The present system is integrated into the nutrition intake information.Thus, the device receives a signal relating to the food item that isgoing to be ingested by the user. The signal is generated through anymeans described above in the various embodiments. The controller thenrecognizes the food item and may access information relating tonutrition of that food item. Using that information, a calculator maydetermine the amount of insulin (bolus) needed.

In one embodiment, once the food item is received/recognized by thecontroller, additional information relating to the amount of the fooditem planned to be ingested will be requested from the user. In otherembodiments, this information will only be requested where the food itemincludes greater than I serving size. In still other embodiments, theinformation will only be requested if the food item is generally notintended to be consumed by one person at one given meal or snack time.

In some embodiments, once the food item is received/recognized by thecontroller, along with the user's blood glucose reading, the user mayrequest the controller to “suggest a serving size”. This function willassist the user in determining the amount of any food item the user mayingest. In some embodiments, this determination is based solely on theblood glucose reading. In other embodiments, this determination is basedon the blood glucose reading together with trend data for blood glucosereadings. Additional factors the controller may take into considerationare accumulated caloric intake, exercise information and/or illnessinformation. In some embodiments, the controller may additional requesta body temperature reading or other additional information beforecalculating and recommending food items or quantities of food items.

In the various embodiments, these options may either be user optionsthat are pre-set by the user, or can be pre-set and require the user toturn them off. In still other embodiments, the user preferences mayinclude food items where the user requests the controller not to ask theserving size, and those food items where the user wishes the controllerto prompt the user to enter the serving size (i.e., where the servingsize is required).

The term “serving size” may mean the actual serving size determined by afood item producer, by a nutritional standard, or a recipe, or can referto an entry of the weight, size or number of items a user intends toingest. The database uses this serving size information to calculate theinsulin dose recommended and/or, to track the user's food intake.

In some embodiments, the food management is performed by an insulin pumpand controller system, where there is also continuous glucose monitordata collected by the controller (and/or pump) at intervals.

In some embodiments, the food management system utilizes a glucose meteras the device, and the user either enters the insulin they intake, or,in the case where the diabetic using the glucose meter is not also usinginsulin, information relating to other drug intake is entered. In someembodiments, functionality that is described above with respect to theinsulin pump and/or controller is also imparted to a stand-alone glucosemeter.

Additional functionality in the various embodiments of the insulin pump,insulin pump and controller, insulin pump and controller and glucosemonitor, insulin pump and controller and glucose meter, or stand-aloneglucose meter, include recommendation and limitation functionality. Forexample, the device, upon recognition of the food item, may determinethe food item is either “acceptable” or “not-acceptable” for the user atthat time (or anytime, depending on the user profile). Thisacceptability factor may be determined based on blood glucose readings,accumulated caloric intake, or both.

In addition to tracking food ingested by the user, in this embodiment,the food management system may additionally provide recommendations offood to be ingested or limit food intake. These recommendations arebased on user preferences which are entered into the user profile. Inthis way, the profile may include recommended snacks, quantities or fooditems in response to particular blood glucose readings. Additionally,recommendations based on time of day or planned exercise may be made.Also, limitations based on the same profile may include limiting caloricintake to a maximum per day or per time period, limitations of certainfoods, and making recommendations not to ingest food when the user has aparticular range of blood glucose readings.

For example, the device may either receive a manual input of a glucosereading or receive it automatically. With respect to receiving the dataautomatically, this occurs where the device is implemented in an insulinpump remote controller with a glucose meter built in, or in the case ofa controller that doubles as a continuous glucose monitor controllerreceiving regular readings from an injected glucose sensor (or,alternatively, on an insulin pump itself receiving either transmittedglucose readings either from an continuous glucose monitor or from aglucose meter, or otherwise manually entered). Readings may be in mg/dlor mmol/L. Where the reading indicates a low glucose reading, a messagemay appear to the user saying, for example, “eat a snack”, or “do youwant a snack?”. The exact wording of the message may vary. Following aresponse from the user, the display may include a recommended snack, forexample. “3 oz of orange juice”. These messages may be pre-programmed bythe user with their preferences. These comments may also be audio, audioand visual, and/or accompanied by a light or vibration or other alarmindication.

These comments may be accessed by someone other than the user as well.For example, if a diabetic looks unwell, a friend, family member orotherwise third party may view the device and see the message “do youwant a snack?”, select “yes” and the device will list to the third partya suggested snack or a number of options for a snack. Additionally, thedevice could include instructions to the third party of what to look forand how to help the diabetic.

Other embodiments include, upon the request of the user, arecommendation for a meal or a snack if the user is hungry. The user mayselect from a menu “I want a snack”, or “I want lunch”, or simply “I amhungry”. In response, the device, knowing the user's medication intakeand blood glucose level, as well as the time of day, can recommend atype of snack or a type of meal. Additionally, the device may recommenda list of options. For example, if the user's blood glucose level iswithin an acceptable range, when the user requests “I want a snack”, thedevice may list a number of food options that will not affect the bloodglucose level negatively. For example, a sugar free gelatin product,sugar free ice-pop, club soda, or other non-nutritive food items thatmay satisfy the user's craving without negatively impacting their bloodglucose levels.

Additionally, where the device includes an RFID reader, the device maydirect the user to a snack option in which the RFID reader has locatedbased on an RFID transponder signal.

Also, if the user desires a snack, and the blood glucose readingsindicate a range where it would be preferable for the user to eat asnack, the device may indicate a list of suggested snacks that the userhad entered into the profile to be eaten when their blood glucosereadings were within a particular range. Other options may be that theuser may select “salty snack”, or “crunchy snack”, and the device maysuggest preferable foods depending on the profile and blood glucosereading.

NEW DATABASES AND PROFILES. In one embodiment, the device may downloadcategory specific databases and profiles. For example, a user maydownload a specific database or register their device to receive accessto a specific database. These specific databases may be diet specificdatabases, brand specific databases, goal specific databases or interestspecific databases.

In some embodiments the databases are learning databases. Thus, thedatabase learns a particular user's preferences and makesrecommendations based on those preferences, or assists the user withmaking lists or planning based on past user preferences.

SMART VENDING MACHINES. One embodiment of the system is implemented witha vending machine capable of communicating with the device. The vendingmachine communicates the food items present. This communication is doneusing a transponder, or any signaling means discussed above. In someembodiment, the vending machine transmits the nutritional information,however, in other embodiments; the device references the database fornutritional information.

In some embodiments, the food items each include a transponder or RFID,and signal to the device. Thus, the RFID transponder is in the food itempackaging in this embodiment.

In some embodiments, the device may be used to browse through theavailable products in the vending machine, and the user may view thenutritional information and price. The user may also receiverecommendations from the device based on their user profile. Theserecommendations include those based on the food items ingested for theday, time of day and blood glucose readings, caloric or monetaryallowance remaining, activity levels, etc. In some embodiments, the usermay purchase the item in the vending machine using the device and theelectronic account. In other embodiments, the user purchases a food itembased on recommendations from the device, but manually purchases theitem.

In some embodiments where third parties have put locks on the device,this device will only be able to purchase particular food items from thevending machine. Additionally, the device may track the calories andother nutritional information of the food items ingested throughelectronic purchase of the food items.

In some embodiments, as the vending machine is loaded, each slot isreprogrammed with the bar codes of the product, or through RFIDtransponders on the slots only (i.e., in this embodiments, the productpackages themselves do not necessarily contain an RFID transponder,however, the slot where the products are loaded do contain an RFIDtransponder). The device recognizes the vending machine and knows theproducts located in each slot based on a database update. In this way,each vending machine may be loaded differently, thus, standardization isnot required.

In addition, the device may communicate with an online database whichmay include up-to-date information regarding, for example, the locationand contents of vending machines. Thus, as user may use the device tosearch for a particular food item, or for any recommended food itemswithin a certain desired proximity of the location of the device.

In some embodiments, when the device is within a particular proximity toa vending machine, the vending machine may signal to the device and thedevice may alarm or otherwise indicate same to the user, either audioand/or vibration and/or visual and, in some embodiments, this indicationmay additionally contain a displayed ad or other message on the UI tosignal to the user.
